Pleural Tissue Samples Collection in Determining the Stage and Prognosis of Patients with Mesothelioma

This trial studies pleural tissue samples collected during biopsies to test a new method for determining the stage and prognosis of patients with malignant pleural mesothelioma. This new method may allow doctors to better classify cancer stage and give a better estimate for prognosis prior to surgery or another treatment.
